DEUTA SiFa Safety System

The Safe Product Package

The DEUTA DSD Safety System is a SIL certified product package, consisting of the safety unit DEUTA REDsafe and either two wheel pulse sensors or pick-up sensors. The standard SIL system is the on-board extension of track based safety systems such as intermittent automatic train control PZB, continuous automatic train control LZB and the European Train Control System ETCS. The system concept corresponds to the safety-related application conditions SIL 3 for DSD, with due regard of standstill detection, monitoring of maximum speed and monitoring of limit speed.
